F200 Type B for smooth DC residual currents and operational safety, all-current sensitive, with a short delay of 10 ms, surge current resistant up to 3 kA (5 kA in selective version). Residual current protective devices (RCCBs) provide protection for persons and property as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. The residual current circuit breakers of the F200 series ensure protection against earth faults for sinusoidal alternating currents, pulsating currents, and smooth DC residual currents. They also provide fault protection (protection against indirect contact), additional protection (with IΔn ≤ 30 mA), and fire protection (with I∆n ≤ 300 mA). They meet the product standards for Type A IEC/EN 61008-1, 61008-2-1, 61543 (VDE 0664 10, 11, 30) and Type B DIN EN 62423 (VDE 0664-40). Their main applications are in commercial and industrial settings. The extensive range of accessories provides everything you need for your installation tasks. RCCB Type B is suitable for non-linear circuits that can generate residual currents with smooth DC residual currents and various (high/low) frequencies. These components are found in electronic devices such as frequency converters. RCCB Type B has a frequency range of 0...2 kHz for detecting the residual current and offers high system availability.
